We have a 2007 launch limited and are currently having a few problems that I would like to know if anybody has some quick fixes for.

The boat is docked and covered every night and it is unable to dry out. We are not able to get out everyday, so over time the humidity builds up under the cover and everything becomes wet. This is a big problem especially because the amps and radios are becoming less reliant due to the moisture.

The dealer informed me that one issue is when it rains, water gets in through the vent just below the window on the driver and passenger side (we have a snap cover :/). Unfortunately that happens to be right where the amps are located. Has anyone sealed these?

Nothing ever good comes from leaving your boat in the water for a long period of time, for as much as you spent on that boat why not pull it out and dry store it when you wont be using it for awhile? Everyone who docks there boats in the water ends up having problems. If you cant pull it out, get a one piece cover, it will work much better than the snap down mooring cover, it is not water tight with the snaps.

The boat gets used probably every three days.. We're not talking weeks at a time. However, if it does rain, water does get in unfortunately. I'll look into a full cover, but I just wanted to know if anything else can be done as well.

Being in Florida we have heard of this. If you have a power outlet you can buy a dehumidifier under the cover. You can put it on a timer so it only runs during the day. I know of a guy that could not stop getting mildew. He did the dehumidifier thing and it worked. Might try that. They are not that expensive.
